Fix infer_arbiter_index for partitioned tables 
The fix for concurrent index operations in bc32a12e0d started
considering indexes that are not yet marked indisvalid as arbiters for
INSERT ON CONFLICT.  For partitioned tables, this leads to including
indexes that may not exist in partitions, causing a trivially
reproducible "invalid arbiter index list" error to be thrown because of
failure to match the index.  To fix, it suffices to ignore !indisvalid
indexes on partitioned tables.  There should be no risk that the set of
indexes will change for concurrent transactions, because in order for
such an index to be marked valid, an ALTER INDEX ATTACH PARTITION must
run which requires AccessExclusiveLock.
